Question

I tried the Number 7 trick, but the answer is always 1,001. Am I doing things right?

Community Answer

Question

I want to try some tricks involving a calculator and lots of people. How can I do it?

Community Answer

Here's what you do. First, get a graphing calculator. Ask for one number from each of the people, and plug it in. Then, tell the audience that you can calculate any number they make into a whole number. Divide by Zero. Bow as the audience applauds!

Question

How do I make a C on the calculator?

Community Answer

On a scientific calculator, use the bracket on the left. It works sometimes but not always; sometimes it doesn't make the word look right.
